The Input Socket
Transducers are connected to a Bridge Amp using the eight-pin DIN
sockets on the front panel. The sockets provide terminals for
supplying a transducer with power and for receiving the transducer
output. Front-ends are supplied with DIN plug kits (one per
connection) to be fitted to those transducers that lack them. The
connection is discussed in more detail later.
The Status Indicator
The Status indicator of the Bridge Amp is located at the bottom right
of the front panel, and the Status indicators of the Quad Bridge Amp
and Octal Bridge Amp are located beneath each connector on the front
panel. When an ADInstruments program such as LabChart starts up,
the Status indicator light should glow green, indicating that the
program has found the front-end, checked and selected it, and is
ready to use it. If the light does not glow when the program is
running, this indicates either that the front-end is not connected
properly or that there is a software or hardware problem.
